Eternal Vow

It has been 17 years now, since I summoned this creature. It was in order by a king, a king long gone by now, who wanted to conquer the world with it. Moral is always dictated by rulers. It was the biggest mistake I ever made. The creature could not be tamed. It had killed hundreds of people before I could restrain it. It should not be set free again. It must not be set free again. Sometimes messengers come by with food, sent by kings to show their gratitude. They even sent people to replace me, but those are actually the saddest moments. They never make it to the pillar.
